Whether online or in the local pet store, there are a bewildering variety of pet healthcare products and services to choose from. Diets and supplements, ancient herbs and folk remedies, and even high-tech treatments like hyperbaric oxygen tanks and laser therapy. Everything promises to give your pet better health and a longer life, and isn't that what every pet owner wants? But how do you know if all of these products do what they claim? Are they safe? If they really are miraculous cures, why are so many offered only on the internet or by a few veterinarians specializing in "alternative medicine?" Brennen McKenzie, a vet with twenty years of experience and the former president of the Evidence-based Veterinary Medicine Association, helps pet owners and veterinary professionals understand the claims and the evidence, allowing them to make better choices for their companions and patients.
